Question

How do you find the slope of a line segment connecting points A(4,-5) and B(-5,8)?

Answer 1

Solution:

Let A(4,-5) = (x1,y1)

B(-5,8) = (x2,y2)

Now ,

Slope of the line segment AB

(m) = (y2-y1)/(x2-x1)

= [8-(-5)]/[-5-4]

= (8+5)/(-9)

= -13/9

Therefore,

slope (m) = -13/9

•••

Answer 2

A(4,-5)=x1=4,y1=-5

B(-5,8)=x2=-5,y2=8

y2-y1/x2-x1

8-[-5]/-5-4

8+5/-9

-13/9

Therefore the slope of line is 13/-9
